Answer:

$8.72

Step-by-step explanation:

Since the tax rate is 9% of the lunch cost, the tax for this lunch is .72 dollars since 9% of 8 is 0.72(see math below). You add the 0.72 to 8 and the total cost is $8.72.

8 x (9/100) = tax

8 x 0.09 = 0.72

8+0.72 = $8.72

Write the equation of the line in slope intercept form that passed through (1, 4) and (3, 18)

romanna [79]

Answer:

y=7x+11

Step-by-step explanation:

to find the slope we need to do $\frac{18-4}{3-1}$ which is $\frac{14}{2}$ or 7.

then, we put this into point slope form (y-y1)=m(x-x1).

y-4=7(1)

we make the x value 0 in order to find the y-intercept.

y=11 since we multiply 7 by 1 to get 7, and add 4 onto both sides.

then we put the slope and the y-intercept into slope intercept form and get y=7x+11.

While driving in an exotic foreign land, you see a speed limit sign that reads 180,000 furlongs per fortnight. How many miles pe

erma4kov [3.2K]

Answer:

66.96

Step-by-step explanation:

Furlong = 1/8 mile

Fortnight = 14 days

Day = 24 hours

If the speed limit is 180,000 furlongs per fortnight, converting the units from furlongs per fortnight to miles per hour:

$V=180000\frac{furlong}{fortnight}*\frac{1\ mile}{8\ furlong}*\frac{1\ fortnight}{14\ days}*\frac{1\ day}{24\ hours} \\V=66.96\ mph$

The speed limit on this exotic land in 66.96 miles per hour.

Elisa is making strawberry shortcake. One serving of strawberry shortcake requires one third cup of strawberries and one shortbr

Kisachek [45]

Given, To make a strawberry shortcake for one person, we need :

▪︎ $\frac{1}{3}$ cup of strawberry

▪︎one shortbread biscuit

Quantity of strawberries Elisa has = 3 cups

Number of shortbread biscuits she has = 12

Number of shortcakes she can make :

$= \tt3 \div \frac{1}{3}$

$= \tt\frac{3 \times 3}{1}$

$\color{plum} =\tt 9 \: people$

Thus, Elisa can serve strawberry shortcakes to 9 people.

With 12 dozen shortbread biscuits she can serve 12 people.

Quantity of strawberries needed to serve 12 people :

$=\tt \frac{1}{3} \times 12$

$=\tt \frac{12}{3}$

$\color{plum} = \tt4 \: cups$

<h3>○=> Therefore :</h3>

▪︎Elisa can serve strawberry shortcakes to <u>9 people</u>.

▪︎Elisa will need <u>4 cups of strawberries</u> if she wants to use all dozen shortbread biscuits.
